Yeah I'm confident that Bomb and base Bang are both significantly weaker than GS, also probably a bit slower.
AP wise though, I think Darkshine's interactions with ENW and Psykos both point to him being stronger than regular Atomic. The Superalloy missile knocked Psykos unconscious, which was more than the Beeline Atomic Slash did
That depends on the AB multiplier, which is very hard to guess actually. On the one side, as we established earlier:
*I argue Darkshine is stronger than before because, despite having fought Bang in the past, he has continued training non stop, and he also stated that he is looking for a competitive fight (although this could be because no one has been able to damage him).
base Bang's AP < weaker Darkshine's durability < current Darkshine's durability < (one shot) Golden Sperm < (implied one shot level) Platinum Sperm = around Awakening Breath Bang.
This implies AB Bang is a one shot level above base Bang. However, this is only if you agree that PS is stronger than GS (I do, btw) , and that AB Bang is relative to PS (Garou could have gotten stronger after waking up/ taking damage). But, is AB Bang actually a one shot level above his regular self? Let's look at the evidence:
- Garou evolves massively against Orochi, to the point that he can tank attacks (Orochi's punch) stronger (presumably, because Orochi is trying harder and trying new techniques) than initial attacks (horns) that put holes in his body, and so fast that he went from having trouble and getting tagged by one horn, to doding all 8 horns almost simultaneously. After evolving so much, he decides to use an imperfect version of Awakening Breath on Orochi. The main point here is that he thought that he could get the job done with AB, although he could have kept evolving at an impressive pace. This would grant imperfect AB a boost higher than Garou's reactive evlolution during the Orochi fight.
- Asleep Garou uses imperfect AB on Darkshine and his strength doesn't seem to change much after waking up (assuming he lost it when he woke up).
- Garou uses imperfect AB against the A class squad in the forest, and he gets better but his durability and AP don't seem to change much, just his coordination and cognitive ability to turn the fight upside down.
- AB Bang clashes briefly with Garou (who just overcame a weakened Bomb, who should be relative to base Bang according to Fubuki). Not only that, but when Garou starts using perfect AB as well, his strength doesn't seem to vary, he even overcomes AB Garou while he didn't deal damage to a non AB Garou.
All in all, AB has many different interpretations, is extremely inconsistent, and as such such be examined more deeply.
You can't compare Superalloy Missile and Beeline Slash. Jetrochi's body literally morphs, it can change its shape continuously and even if it couldn't, it would be very hard to determine whether being cut in half is worse than being kicked out of the fusion/ being squashed, etc. Bang and Bomb together, who we established as higher in AP than Darkshine, perform their combined strongest technique on Goo Orochi and the visible damage is either hard to compare to the other heroes' attack, or less effective. That would be a contradiction unless we face the reality that Orochi's body is constantly changing size and form.
